Reports unnecessary <code>this</code> qualifier.
<p>
  Using <code>this</code> to disambiguate a code reference is discouraged by many coding styles
  and may easily become unnecessary
  via automatic refactorings.
</p>
<p><b>Example:</b></p>
<pre><code>
  class Foo {
    int x;
    void foo() {
      this.x = 2;
    }
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  class Foo {
    int x;
    void foo() {
      x = 2;
    }
  }
</code></pre>
<!-- tooltip end -->
<p>
  Use the inspection settings to ignore assignments to fields.
  For instance, <code>this.x = 2;</code> won't be reported, but <code>int y = this.x;</code> will be.
